Hello everybody.

One day, I turned my computer on and I realised that every black area was flackering a red color. As my desktop was mainly black too, it seemed like some big red area, but the icons were still having a black "shadow" to the right.

I tried updating the driver of my graphic card, but it didn't help. (Anyway, why would it be the problem, if it worked well before?)
I changed the settings of the graphic card: just increasing the gamma to 1 more and there is no problem anymore (except when it boots up of course)

Technically I just got lightly around the problem, but didn't really solve it. I believe it may be a g-c problem. Or could it even be thescreen itself? Any help would be appreciated, thanks.

I have an NVIDIA GeForce4 Ti 4200 with AGP8X

Thanks in advance

I've noticed something similar with my PC.
Every time I boot, when I try to play videos, the gamma is messed up, so I have to go into my NVIDIA control panel and flick the gamma up, apply, back to normal, then apply again, and she's apples until next boot.

No idea why either.
I did, however, update something to do with my Graphics card somewhere along the lines (don't think it was the drivers as they're a big download) - I think it might have just been the control panel or something... Not sure.

I've had two occasions where something like that has happened to me.

The first was a dodgy video cable, and the second was when I had my video card pop out slightly from the interface. Yours sounds more like my cable problem than anything else.

Thanks for the reply, guys.
I tried following IanM's advice an disconnected and reconnected every single cable in and outside of my computer. ... Nothing changed.
And now worse. two days later ... It works perfectly again.
